DRIVING MECHANISM.-

Application filed May 28, 1915.

To all whom it may concern:

Be it known that I, ALEXANDER BozYM, a subject of the Czar of Russia,residing at Charleroi, in the county of Washington and State of Pennsylvania, have invented certain new and useful Improvements in Driving Mechanism, of which the following is a specification.

This invention relates to certain new and useful improvements in driving mechanism.

The primary object of this invention is to provide a churn mounted upon a rocking chair and adapted for operation by the rock ing of an occupant seated in the chair and whereby the usual rocking of the chair is utilized for the usual operation ofthe churn.

A further object of the invention is to provide a churn having a rotatable dasher movable longitudinally of the churn by power exerted upon the dasher at the opposite ends of the churn and providing an inexpensive device by which more perfect churning is accomplished.

WVith these general objects in view and others that will appear as the nature of the invention is better understood, the same consists in the novel combination and arrangement of parts hereinafter more fully described, illustrated in the accompanying drawings and pointed out in the appended claim.

In the drawings forming a part of this application and in which like-designating characters refer to corresponding parts throughout the several views, Figure 1 is a side elevation of the device operatively mounted upon the rockers of a chair. Fig. 2 is a rear elevation thereof. Fig. 3 is a central longitudinal vertical sectional view through the device. Figs. 4c, 5, and 6 are transverse sectional views taken respectively upon lines IV-IV, VV and VI-VI of Fig. 3.

Referring to the drawings, it will be seen that the invention consists of a barrel-churn 10 mounted by means of opposite brackets 11 secured to the bottom thereof to the rearwardly extending rockers 12 of a rocking chair 13, the said brackets being removably engaged with the said rockers by means of clamps 14: and by which arrangement the churn is supported by the rockers.

A. spiral operating shaft 15 is axially positioned through the churn having its spiral or twisted portion 16 slidably mounted through the central opening 17 of a bush- Specification of Letters Patent.

ing 18 carried by the churn bottom 19, and

whereby the inward and outward movement of the shaft 15 impart-s alternate revolutions thereto. A stuffing box is provided for the shaft 15 in the bottom of the churn consisting of a screw-threaded circular block 20 through which the shaft extends and having a packing 21 interposed between the same and the afore-mentioned bushing 18.

A dasher in the form of a disk 22 is secured by-means of a set screw 23 to the shaft 15'interiorly of the churn and is provided with a plurality of perforations 24; extending therethrough, while interposed blades 25 are perpendicularly arranged upon the upper face of the said dasher, each provided with a perforation 26 extending through the same.

A detachable cover 27 is provided for the churn being removably secured thereon by means of suitable clamps 28, while the dasher shaft 15 extends through a central perforation 29 thereof. A post 30 is centrally mounted upon the churn cover 27 being provided with an axially arranged thrust bearing socket 31 for receiving the upper rounded end 32 of the dasher shaft 15, while a helical spring 33 surrounds the said post and has its opposite ends secured respectively to the cover as at 34 and the upper end of the post as at 35.

It will be seen that a person seated in the chair 13 and rocking in the usual manner will force the rear ends of the rockers 12 toward the floor or permanent support 36 upon which the chair is positioned during the rearward rocking movement. This action lowers the churn 10 and the bottom curved end 37 of the dasher operating shaft 15 being in contact with the floor, the said shaft allows the churn 10 to be forced downwardly upon the spiral portion 16 of the said shaft and as the churn is prevented from revolving by its engagement with the rockers 12, the shaft 15 will be thereby made to revolve in one direction, while the dasher disk 22 revolves therewith and is forced upwardly within the churn, the contents of the churn passing through the disk perforations 24: and the blade perforations 26. When the lowermost position of the rockers and churn is reached, the journaling post 30 will be positioned at the limit of its movement farthest from the churn top 27 and with the spring 33 under compression so that a forward movement of the chair allowing an up- Copies of this patentmay be obtained for Ward and releasing movement'of the rockers forces the post 30 downwardly and the operating shaft in a similar direction through the bushing opening 17, thus revolving'the dasher disk in an opposite di- -lVhile the form of the invention herein .shown and described is What is believed to be the preferred embodiment thereof, it is nevertheless .to be understood that minor changes maybe made therein Without departing from the spirit and scope of the invention as claimed.

WVhat I claim as new is Driving mechanism including a vertical shaft, spiral threads formed on said shaft for a portion of its length, a member slidably mounted on said shaft and adapted to rotate the shaft When passing the spiral portion, a block carried by one end of said shaft, acoil spring surrounding said block and connected at one end thereto and at its other end to said member to return the shaft to normal position When rotated in one direction by said member and operating means for said member.

In testimony whereof I aifix my signature.
